Best Buy Co. announced that founder Richard Schulze would step down as chairman after an independent board investigation found that he had failed to report allegations of personal misconduct by former CEO Brian Dunn to the board's audit committee.

Fresh off the resignation of CEO Brian Dunn and the revelation that the company lost a not-so- insignificant sum of $1.7 billion last quarter, Best Buy’s recent announcement to close 50 stores by the end of 2012 probably didn’t come as a surprise to anyone in our industry.

Best Buy’s announcement on Tuesday morning that its CEO Brian Dunn had resigned the company by mutual agreement has been updated with information that a review is being conducted concerning the former chief executive’s personal conduct.

Elaborating on previously announced plans to downsize its brick-and-mortar footprint, Best Buy CEO Brian Dunn said this week that the electronics retailer is launching plans to wall off parts of its big-box stores and sublease the space to smaller retailers, such as grocers, beauty supply stores, home furnishing outlets and others.
